Faber,Chicago, Ill., assignor to General Regulator Corporation, Chicago, Ill.,a corporation of Illinois Application August 25, 1933, Serial No.686,849 s claims. (c1. 984-94) at the line 2 on Fig. 1 and viewed in thedirection-J-` My invention relates, more particularly, to ventilators ofthe type comprising a panel for installation in a window of a room to beventilated and more especially at the top of a window having the usualsliding sashes, the panel being equipped with a Ventilating fan as forexample of the electrically driven type.

One of my objects is to provide a construction of ventilator forapplication to the top of a Winl'O dow, the panel portion of which maybe readily adjusted from its position of use in which it extends intothe path of upward movement of the lower window sash into a positionpermitting of the raising of this sash the full height.

l'5 Another object is to provide a construction whereby the fan may beused either to withdraw air from, or discharge air into, the room asdesired and at diiierent angles as desired.

Another object is to provide a construction having an electric fanmounted to be adjusted into positions for discharging air from, or into,the room, whereby interference between the fan and the wires leading thecurrent thereto will be prevented.

Another object is to provide a construction of panel formed in part ofglass plates, whereby the plates may be easily and readily secured inplace in the panel frame, permitting of the shipping of the glassseparate from the frame of the panelwith reduced danger of breakage-andpermitting ready substitution in case of breakage.

Another object is to provide a novel construction of mounting for themotor whereby the construction is adapted for the ready assemblytherewith of motors of diierent makes and cooling of the motor isaugmented.

Another object is to provide a construction whereby the mounting for thefan may be readily assembled with the panel, making it commerciallyfeasible to ship these parts in separate packages to reduce possibilityof damage.

Another object is to provide a ventilator structure which will be ofsimple construction, of light weight and durable and Where formed inpart of glass less liable to breakage of the glass than structures ashitherto provided; and other objects as will be manifest from thefollowing description.

Referring to the construction shown in Figs.

1 to 8, inclusive, I5 represents the vertical side members of a windowframe; I6 the top crossA 35 member thereof; I'I the upper, outer,vertically slidable window sash; and I8 the inner, lower, verticallyslidable window sash, respectively, all as commonly provided in windowconstructions of' this type. 40

Loc-ated atthe top of the window opening are Ventilating means embodyingmy invention and functioning to produce air flow between the top of thewindow casing and the top of the outer sashv I 1 when in the partlylowered position shown 45 in Fig. 2.

The ventilator shown comprises generally stated a panel section I9preferably formed of telescoping sections as hereinafter described toadapt it to fit in window openings of different 50 Widths, a fan devicerepresented generally at 2D located in an opening in the panel and meansfor supporting the panel and the parts carried* thereby in the operativeposition shown in Fig. 2 and adaptingv these parts to be displacedinwardly to 55 opening channel the position shown in Fig. 3 in which thelower sash I8 is free to be raised the full height.

The panel I9 is shown as comprising a main panel section 2I formed of arectangular sectional frame 22, a sectional ring frame 23 intermediateits ends, and glass plates 24 forming closures for the ends of the panelsection 2|; the panel I9 also comprising supplemental panel sections 25at the ends of the panel section 2I and adjustably telescoped therewith.

Referring to the details of the illustrated panel section 2|, the frame22 comprises two similar rectangular frame sections 26 each formed ofsimilar bars of angle shape in cross section mitered at their ends, theframe sections 26 being so positioned as shown as to form aninwardly-opening channel 21 extending entirely around the frame 22 inwhich bars 28, as for example and preferably of wood and of angle shapeas shown, are located to provide an inwardly- 29 extending continuouslyaround the frame 22 into which the plates 24 extend, with packing strips30 interposed between the edges of these plates and the bars 28.

The frame 22 is thus formed of separate frame sections disposed face toface and which when separated permit of the setting of the glass plates24 with the packing 30 and bars 28 into one of the sections 28 of theframe 22 and the secure clamping of these parts'together upon theassembling of the other frame section 26 therewith to the position shownin the drawings in which it is securely held as by bolts represented 3!passing through the frame sections 26 and the bars 28. The adjacent endsof the plates 24 spaced apart as shown at the center of the Ventilator,are of arcuate shape as represented at 32 adapting them to be assembledwith, and clamped by, the ring frame 23`as hereinafter described, thewood bars 28, at the upper and lower portions of the frame 22 being alsospaced apart, their inner terminal ends being represented by the dottedlines 33.

The ring frame 23 comprises a pair of flatwise opposed ring sections 34and 35 having extensions 36 and 3l, respectively, at their upper andlower ends, these extensions being-located within the channel formed bythe frame members 26 and in the spaces between the plates 24 and thebars 28 and secured in position in the frame 22 by bolts represented at38.

The opposing surfaces of the rings 34 and 35 are annularly recessed asrepresented at 39 and respectively, thereby forming an inwardly openingchannel into which the arcuate portions 32 of the glass plates 24extend, with packing strips 4I interposed between these plates and thewalls of sad channel, the plates 24 being clamped in position by screws42 engaging these ring sections.

The internal diameter of the ring section 35 is larger than the internaldiameter of the ring section 34 thereby causing the latter ring sectionto present an annular flange 43 about its inner periphery to which themounting hereinafter described for the fan 2B is secured.

The supplemental panel sections 25 each comprises a plate member 44shown as located at the outer face of the panel section 2l and having atits upper edge an inwardly and downwardly turned flange portion 45 andat its lower edge an inwardly and upwardly turned flange portion 46adapting the sections 25 to be telescoped with the ends of the panelsection 2l, these panel sections being held in their positions 0fadjustment relative to each other by bolts 41 extending horizontallythrough the panel sections 25 and through horizontally elongated slots48 in the ends of the upper and lower members of the frame 22.

rlhe mounting above referred to for the fan 2i) is shown as comprising aring 49 having an annular peripheral flange 50 fitting against theflange 43 of the ring frame 23 and secured thereto as by the screws 5I.The ring 49 is provided with diametrically opposed upper and lower lugsi 85.? and 53 in which vertically extending trunnions 54 and 55 of afan-supporting member 56 are trunnioned thus swiveling the member 56 onthe ring 49 to permit the member 56 and thus the fan to be adjusted intodifferent positions about a vertical axis, the lower trunnion 55 whichis of tubular form having screwed thereon a nut 51 for holding themember 56 in adjusted position.

The fan device 28 is shown as comprising an electric motor 58 mounted onthe member 56 and a fan-propeller 59 mounted on the outer end of theshaft 63 of the motor and positioned in the opening in the ring 49, butwith suiicient clearance to permit the member 56 and the parts carriedthereby to be rotated on the trunnions 54 and 55 for adjustment Withoutobstruction.

The portion of the member 56 at which the motor 58 is connected, isformed with a circular recess or socket portion 5I containing a centralopening 52 and into which the adjacent end of the motor extends, themotor being secured therein in spaced relation to the end wall and thesurrounding wall of the recess 6I as by screw bolts 63 extending throughthe end wall of the recess 6I and into the motor casing, with spacers,one of which is shown at 64, surrounding the screw bolts 63 andinterposed between the end wall of the recess 6I and the adjacent end ofthe casing of the motor, the arrangement just described not onlyadapting the member 55 for the application thereto of motors ofdifferent makes, but also permitting of free circulation of air overthat end of the motor at which the latter is supported.

The wires for conducting current to the motor 58 extend through thetrunnion 55 thereby avoiding tangling of the wires with any of the otherparts of the construction particularly in the adjustment of the motorsupport on its trunnions.

In the particular construction shown the ventilator comprises as a partthereof any suitable switch mechanism of the pull cord type forcontrolling the operation of the motor. Such a switch mechanism isrepresented at 65, it being shown as secured in a recess 66 provided inthe enlarged portion 6l of the member 56 forming a housing therefor andrendering the switch mechanism concealed when the motor and fan assemblyare adjusted in a position for withdrawing the air from the room. In thearrangement shown the wires through which current is f supplied to themotor are represented at 68, 59, 19 and 1I, the wires 68 and 69extending from any suitable source of current and through the Referringnow to the means for adjustably support-ing the panel I9 and the partscarried thereby in position at the top of the window, these meanscomprise upper and lower inwardly extending brackets 'Ill and 'I5 on theterminal end portions of the panel sections 25, these brackets, shown asformed integrally with the plate portions @il of these panel sections,presenting forwardly opening recesses 'I6 and Il,

respectively.

These supporting means also comprise bars 'I8 secured, as by screws Ita,flatwise against the inner surfaces of the window frame members I5inwardly beyond the path in which the lower window sash i8 is movable.The brackets Ill and 'I5 are connected with the bars 'I8 by means oflinks 'I9 and 89, respectively, the links 'E9 and B being pivotallyconnected at their lower ends with the bars iii as represented at B! andS32 and at their upper ends with the brackets 'I4 and l5 as representedat 83 and 8d, respectively.

The parts just described are so constructed and arranged as shown thatthe panel I9 may be swung outwardly to the position shown in Fig. 2 inwhich it substantially closes the opening at the top of the window, theupper sash being lowered to the position shown, in which position thepanel extends into the path of upward movement of the lower sash i9, ormay be swung inwardly into the room to the position shown in Fig. 3 inwhich the panel I9 is removed from the path of upward movement of thesash I9 thereby permitting the latter to be raised the full height.

The panel I9 is shown as releasably held in the position represented inFig. 2 by wing nuts 95 and 99 screwed upon the ends of studs 8l and 99extending laterally from the bars I9, these studs becoming entered,respectively, in the recesses 'I6 and 'Il of the brackets 'I4 and 15 inthe swinging of the panel I9 to the position shown in this ligure andthe wing nuts 85 and 89 being turned down against these brackets t0clamp them against the bars I8.

Upon releasing the wing nuts 85 and 86 and swinging the panel I9inwardly as shown in Fig. 3 the plate portions 415 of the panel sectionsabut the links 'i9 and 89 and the wing nuts 89, thus limiting the inwardswinging of the panel beyond the desired position.

The construction shown in Figs. 9, l0 and 11 represents an embodiment ofmy invention, as to certain features thereof, in a ventilator in whichthe' panel portion is unprovided with glass sections. This constructioncomprises a panel represented generally at 89 and corresponding with thepanel I9 and shown as formed of a sheet metal main panel section 99having upper and lower inwardly extending anges 9I and 92 and a centralopening 93 at which a ring represented at 94 and corresponding with thering 49 is secured as by screws 95.

The panel 89 also comprises supplemental end panel sections 99 whichslidably telescope with the ends of the panel section 99. To this endthe panel sections 99 are provided at their upper edges with inwardlyand downwardly extending flanges 9'! and at their lower edges withinwardly and upwardly extending flanges 98 which receive the flangedupper and lower edges of the panel section 90. The anges 9| and 92contain elongated slots extending lengthwise thereof as represented at99 of the flange 9| into whichbolts |00 on the supplemental panelsections 96 extend, thereby permitting of the relative adjustment of thepanel section is to lit windows of different widths.

The panel 89 is shown as provided with means, for supporting it in aWindow casing, of the same construction and operating in the same way asthose shown in Figs, 1 to 8, inclusive, and therefore detaileddescription thereof appears to be unnecessary.

It will be noted that the wires leading to the motor and shown aslocated in the hollow portion of member 56 are shielded from the airflowing to the ian blades and thus protected against the deposit thereonof lint, dust or grease when the fan is used -to exhaust air from aroom, it being desirable that the hollow portion of member 55 be closedat its open side as by a cover plate repreand altered and the inventionembodied in other forms o structure without departing from the spirit ofmy invention.
